Yes it really is a scam. This site operates off an extremely broken system. Leave it free for the person submitting the quote but charge a hefty fee to the artist. This introduces the age old problem of "window shoppers" into the equation where they don't actually have interest in buying they just want to see the price for whatever reason. How hard would it be for people to input fake quotes and drive a competitor away from the site? You say it's "up to us" to land the job but your allowing the jobs to never exist in the first place. You know how many quotes I sent out to 16 year olds looking for a makeup artist before consulting their parents? Fix your system.
